Patent CA-2204543-A1 (CA)
Title: Bioactive coating for harvested commodities
Inventor: WILSON CHARLES L
IPC: A23L29/275
Filed: 1995-10-31
Abstract: A bioactive coating composition which comprises a modified chitosan matrix con-taining a yeast antagonistic to postharvest pathogens. Chitosans were not expected to be useful in combination with antagonistic yeasts due to their antifungal properties. However, certain antagonistic yeasts were found to be compatible with modified chitosans and use-ful for the control of decay and ripening. The combination of modified chitosans with antag-onists makes it possible to exploit the anti-fungal and eliciting properties of chitosan, as well as the biological activity of the antago-nist.    The complexity of the mode of action displayed by combined alternatives makes the development of pathogen resistance more dif-ficult and presents a highly complex disease deterrent barrier.

Title: Process for bonding wires to oxidation-sensitive metal substrates which can be soldered
Inventor: MEYER HEINRICH
IPC: B23K1/20
Filed: 1995-11-28
Abstract: In order to bond unhoused semiconductor circuits (chips) electroconductively on circuit boards, the surfaces of the copper structures are generally coated with a nickel layer which is then coated with a layer of gold in order to be able to produce wire connections between the circuit and the conductive structures on the circuit board. The connection between the wire and the connection sites on the circuit, on the one hand, and the conductive structures on the circuit board, on the other, is formed by pressure welding, in particular ultrasound bonding. A novel process by means of which organic protective layers are deposited on the copper surfaces on the circuit board prevents the formation of oxide layers and other impurities on the copper surfaces and thus permits direct connection of the wire by ultrasound bonding to the copper surfaces without impairing the ability of the surfaces to be soldered.

Patent CA-2222237-A1 (CA)
Inventor: WOLFE DOUGLAS E
IPC: G02B6/38
Filed: 1997-11-25
Abstract: The fiber optic interconnection apparatus includes a receptacle mounted at least partially within a wall of an enclosure, such as an optical network unit, a network interface device or a splice closure, and a fiber optic cable assembly for mating with the receptacle.  By mating the fiber optic cable assembly with the receptacle in a predetermined aligned manner, one or more optical fibers of the fiber optic cable on which the fiber optic cable assembly is mounted can be optically interconnected with respective optical fibers held by the receptacle which extend through the receptacle and into the enclosure.  Since the optical fibers which extend through the receptacle and into the enclosure may have been previously terminated, such as during the initial configuration of the enclosure in which the optical fibers are spliced or otherwise connected to other optical fibers or to active equipment within the enclosure, the fiber optic interconnection apparatus permits the optical fibers of the fiber optic cable to be appropriately terminated within the enclosure without requiring the enclosure to be opened.  The components within the enclosure are therefore protected from damage which might otherwise result from opening the enclosure to terminate the optical fibers.

Title: Multiple mode capable radio receiver device
Inventor: LEE MICHAEL C G
IPC: H04B7/26
Filed: 1998-05-12
Abstract: A mobile handset is able to receive and transmit to base stations operating in compliance with different standards, for example CDMA, TDMA or AMPS.  The mobile handset converts the received signal down to baseband and digitizes only a single channel at a time rather than the whole band.          The channel chosen is the biggest of the various transmission systems used.  For example, the channel widths for CDMA, TDMA and AMPS are, respectively 1.25MHz, 30KHz and 30KHz.          Accordingly to deal with these three systems a 1.25MHz channel is digitized.  Thereafter a digital signal processor determines which of the three systems is being used and appropriate processing and demodulation is carried out.
